I wasn't exactly sure where to post this so if it's in the wrong place, please move.

My daughter's laptop will not turn on. the last thing I remember was that she was using it on battery power. when she said there wasn't much battery power left I told her to plug it in. of course that did not happen and I imagine she wore the battery right down. and this might be a stupid question for some but I have not yet experienced this because, alas, I plug my own laptop in as often as I can and don't use my battery very much.

so....my question is: do I just need to buy a new battery? When I press the power button (and it's plugged in) it flashes the green light as if it were going to turn on but then nothing happens. guessing I just need a new battery, yes?

thanks much.

It may be helpful if you were to post the make and model of this laptop. How old is this laptop?

If you have a volt meter see if any voltage is showing. The power adopter has the secondary voltage listed on it, it will be the DC voltage, this is the voltage you should be reading.

Another thing to check is the connector from the power adopter to the laptop. This is a common problem.

If the power adapter proves to be the problem and you are going to replace it remember that you not only have to match the voltage, you also need to match the mA (milliampere) rating.

If you have another power adapter to use on the laptop hook it up and see what happens. Sometimes the adapters fail and need to be replaced.

No battery needed. Do not waste your money on a battery.
You can take the battery out of a laptop and while plugged in it will still work.

As a simple test, take out the battery and see if it still flashes green. Probably not as I suspect that the green flash is from the battery and that no power from the AC Adapter is present.

My guess based on past experience is that:

1.The AC Adapter is not plugged in. Check at the Wall outlet and where that cord plugs into the AC Adapter.
2. The AC Adapter is defective, or the cable from it to the computer has problems.
3. The Small plug that plugs into the computer or the socket in the computer is broken. Look carefully.
4. The DC-In jack connections inside the laptop are broken or the DC-In jack is bad.

Good Luck
